wheels bicycle shop advertised a bicycle for 15% off for a savings of $36. The bicycle did not sell so it was offered at a new 20% discount off the sale price.
What did the bicycle sell for regularly?
What is the amount of the new discount?

original price:
.85x = 36
x = 42.35
originally sold for $42.35
first sale price = $36
another 20% ...
final price = .8(42.35) = $33.88
subtract to get the new discount amount
